TO ALL WHOM IT MAY '.CONCERN:

Be it known that I, B. HUIBE, of No. 2223 Madison street, in the city, county, and State of New York, have invented'a new and improved Rotary Lard Press; and I do hereby declare that the following is a full, clear, and'exactdescription thereof, enabling those skilled in the art to fully understand and use the same, ref'- erence being had to the -accompanying drawing, in which- Y.

Figure 1 representsA a side elevation of this invention partly in section.

Figure v2 is a plan or top view of the same...

Figure' 3 is apartial central sectionof'the same in a larger scale than the previous figures.

Figure 4 is a perspective view of the same.

Similar letters of reference .in the several rigures indicate like parts.

The object of this invention isV to employ centrifugalI force for the purpose of separating the oil from lard or other animal fats, .in contradistinctioh of the .present method of effecting this separation by simple pressure, which requires cumbersome and expensive apparatuses, and much time and labor.

My `rotary press consists of a cylinder, A, which is mounted on the top of a vertical shaft, B. Said cylinder is surrounded 'by a jacket, C, and it is composed rif-an annular grate, D, provided with a lining, E and witha solid bottom, F. v Tle shaft B may be cast solid with said bottom, orV it may be made-of wrought iron and. secured in the'botto'm F by any suitable means. It.is provided with two bearings, and its bottom end is prtected by a east-steelplate, and it is'stepped in a socket, G, which is filled with a series of quoit-shaped disks,1 a a', alternately made of brass and cast iron, so as to reduce the friction to the smallest possible point. The grate D maybe made of a series of wrought-iron rings, which are held at the proper distance apart by thimbles, e, and secured together by screws, f; or said annular 'grate mayalso be east-solid with the bottom F, or a cylin-A der` of perforated sheet metal may be substituted for it. The top g of the'fcylindcr consists of a ring of cast iron, which is fastened in its place by any suitable means. The jacket C is marie of cast iron,'and it serves to receive andv collect the oil, `which runs off into suitable tanks or reservoirs through the' pipe or pipes 7L. The' lining'E of the cylinder A is made of cloth or other suitable fabric of` suiciently fine texture for the purpose, which is heldin place by 'two sets'of steel rings, z'z', one above and one below; or, instead of using these rings, the cloth may also be fastened by securing it to a cylinder, k, of perforated sheet brass, the outer diameter of which is exactly equal to the inner diameter of the grate D. v The steel rings L', a :al also the cylinder lc, (if such is to be used,) are sprung in their places, or secured in any desirable manner. The lard or other aniznnl fat is placed into the cylinder, and, by imparting Vto said cylinder a rapid revolving motion, the liquid portion or oil contained in the fat is expelleda'and the pure lard or fat is retained in tbe-cylinder. This` solid portion remaining in the cylinder is removed by a scoop, G, the point of which is protected by ay cap, n, of leather, or other suitable material, to `prevent `the same from injuring thelining E. By the use of thisv rotary Apress the operation of separating the oil fromlard or other animal fat is rendered easy, and it'can be effected in a short time and with an apparatus which is cheap when compared with the cumbersome presses now usedfor that purpose.

I amawar'e that centrifugal machines have been used to separate sirup from sugar, and -also to expel moisturefrom textile fabrics, or from yarn, but such machines have never, to my knowledge, been used for separating oil from lard; neither could they be used for. this purpose without the lining E, which is essential for this purpose, but which could not be used for separating Sirup from sugar, or for expelling moisture from textile fabrics or yarn. Instead of securing the liningrtothe cylinder A,'the lard may be filled in a bag, and the bag placed loos/ely in the cylinder, without altering theresult.

I do notclaim broadly as my invention the employment of a centrifugal machine for .the purpose of separating a liquid .from a solid body; but,.ha.ving thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. The lining E, made of -cloth or other suitable fabric of suliiciently ne texture for the purpose, in combination with the cylinder A, constructed and operating in the manner set forth.

2. The annular grate D, lining E, and rings i z', in combination with the bottom F and shaft B, constructed and operating substantially as and for the purpose described.
